Enhancing throughput and part quality in injection moulding

A new
plasticizing system for compounds with high levels of glass fibre reinforcement
provides wear-resistance, high throughput, and gentle mixing, enabling
injection moulders to meet the requirements of metal-replacement and other
high-strength applications while enhancing productivity and part quality. The
Xaloy High Glass Filled Polymer System will be introduced by Nordson
Corporation at Fakuma 2017 and is designed for injection moulding a wide range
of resins with filler content from 10 to 60%. Applications include automotive, marine,
electronic, and other parts that require very high levels of strength and
stiffness.

- Xaloy
X-8000 Screw Encapsulation, a nickel-based alloy with high tungsten carbide
content that provides twice the abrasive and corrosion wear life than standard high-velocity
oxy-fuel (HVOF)-applied coatings; Nordson uses HVOF technology to apply the
coating to the entire screw geometry, then fuses the alloy to the parent metal of
the screw, forming a metallurgical bond; in addition, the Xaloy X-8000
encapsulation is double the thickness of standard HVOF-applied coatings;

- Xaloy
X-800 Barrel Inlay, a liner combining a nickel- based alloy with tungsten carbide
that provides a high degree of abrasion and corrosion resistance and functions compatibly
with the Xaloy X-8000 screw encapsulation;

-
application-specific valve, designed to accommodate the viscosity and flow
properties of highly filled compounds.

“Wear-resistance
is only one of the requirements for successfully processing the highly filled
compounds called for in metal-replacement and other high-performance applications”,
said Mark Colella, global product manager for Nordson’s Xaloy brand. “Our new
Xaloy plasticizing system enables moulders to overcome the challenges to
productivity and part quality posed by today’s increasingly higher loadings of
glass fibre reinforcement”.
